Axillary Lymph Nodes

1

• Axillary Lymph Nodes
• Apical - in the apex of the axilla, located along
  the medial side of the axillary vein and 1st part
  of the axillary artery. They receive lymph from
  all other groups of axillary lymph nodes, as well
  as from lymph vessels accompanying the cephalic
  vein. Vessels from the axillary nodes unite to
  form the subclavian lymphatic trunk, which drains
  into the right lymphatic duct.
• Pectoral - 3-5 nodes which lie along the medial
  wall of the axilla, near the inf border of pec
  minor, receives lymph from the anterior thoracic
  wall including the breast.
• Subscapular - 6 or 7 lymph nodes, lie along the
  post axillary fold and subscapular blood vessels,
  receive lymph from the post thoracic wall and
  scapula region.
• Humeral - 4-6 nodes, lat wall of the axilla,
  medial and posterior to the axillary vein.
  Receive almost all the lymph of the upper limb.
• Central - 3-4 large lymph nodes, deep to pec
  minor, near the base of the axilla, receives
  lymph from the pectoral, subscapular, and humeral
  nodes, then drain into the apical group.
